Summary

This PR extracts the core:ui-common image asset ViewModel creation path away from Hilt and routes it through a small Metro-compatible ViewModel graph boundary.

It is part of the broader incremental Metro migration and keeps the runtime behavior unchanged while removing direct Hilt dependencies from core:ui-common.

Changes

• Removed the Hilt plugin and Hilt/resaca-hilt dependencies from core:ui-common.
• Replaced hiltViewModel<RemoteAssetImageViewModel>() in ImageAsset.Remote.paint() with a local Metro ViewModel graph lookup.
• Added ImageAssetViewModelFactory for constructing RemoteAssetImageViewModel.
• Added a generic MetroViewModelGraph / metroViewModel helper in core:di.
• Provided an app-level transitional ImageAssetViewModelGraphProvider through the existing Compose roots:
  • WireActivity
  • CallActivity
  • AppLockActivity
• Added a small Hilt bridge for FileSizeFormatter, because some existing Hilt ViewModels still inject it while ui-common no longer owns Hilt wiring.
• Enabled the Compose compiler plugin for core:ui-common-kmp.

Why

core:ui-common is one of the modules we want to make easier to reuse/migrate toward KMP and Compose Multiplatform. Direct Hilt usage in shared UI utilities blocks that direction and also makes the later Metro migration harder to split into reviewable PRs.

This PR keeps Hilt at the app boundary for now, but removes it from the ui-common image loading path.
